The invention discloses a suspended crucible support with a temperature measuring function for a muffle furnace. The suspended crucible support comprises a sleeve and a combination body. The combination body is provided with a through hole. The sleeve penetrates through the through hole to be fixedly connected. A thermocouple is arranged in the sleeve. A temperature display header is arranged at the top end of the sleeve. The temperature display header comprises a temperature module and a display gauge. Positive and negative poles of the temperature module are connected with positive and negative poles of the thermocouple. The display gauge and the display module are connected and used for measuring and displaying the temperature in a furnace cavity in real time. A hook is arranged at thebottom of the sleeve. A pull ring is arranged on the temperature display header. Scales are arranged on the sleeve. A crucible containing a material is put into the furnace cavity through an exhaust hole in the top of the muffle furnace by means of the support without opening a furnace door, the furnace temperature drop phenomenon caused by opening the furnace door is avoided, ad therefore the precision of an isothermal calcination test is improved. By means of the support, the muffle furnace can meet the test requirements of isothermal kinetics, and the application range of the muffle furnaceis expanded to a great extent.
Description
technical field [0001] The invention relates to the field of testing and analysis, and relates to a device for carrying out thermal analysis tests, in particular to a hanging crucible support for a muffle furnace. Background technique [0002] The muffle furnace is a routine equipment used in the laboratory for hot calcination tests, especially for isothermal calcination tests of solid materials. In the muffle furnace, the heating of the material is mainly radiation heat transfer, that is, the heat is radiated into the furnace cavity through the electric heating wire or the electric heating rod, so as to complete the heat transfer. The inner wall of the furnace chamber of the muffle furnace is equipped with insulation materials, which can reduce heat dissipation and achieve constant temperature. However, when using a muffle furnace to conduct an isothermal test, the furnace door must be opened when the test sample is put in, which will inevitably lead to a sharp drop in the...
